Statement of Qualifications

Stormwater Essentials is dedicated to transforming urban and rural landscapes into vital ecosystems that recycle waste, discharge clean water and air, and sequester carbon. We support facilities, construction and agricultural operations with State of California stormwater discharge compliance. We also design stormwater management plans, erosion and sediment control strategies, and landscape improvements.


Stormwater Essentials is a full-service entity providing a range of services including stormwater discharge compliance, geologic and hydraulic soil investigation, and water resources engineering.

Demonstrated Experience

San Diego Compost Facilities - CA Waste Discharge Requirements

Fully permit and monitor State of California Waste Discharge compliance, prepare and submit documents including Notice of Intent (NOI), Annual Reports, and Technical Reports for several San Diego County Facilities. Bridge the gap between owners and State Water Quality Agencies to convey sound business and manufacturing practices that protect groundwater and surface water in the vicinity of the Facility. 


The NOI/Technical Report is a 20 page document required for State of California WDR permitting which demonstrates the Geologic, Hydrogeologic, and Climatic conditions at the site, as well as the site ownership, operation and maintenance. Information is obtained from past technical studies and online government agency databases, as well as site owners.

Professional Experiences

Kelly (Steffen) Coaty is a principal scientist who has mentored and managed teams of staff engineers and scientists. Kelly has designed, installed, sampled, and reported the results and analysis of hundreds of groundwater monitoring wells and soil gas monitoring wells for the purpose of soil and groundwater assessment and groundwater protection monitoring over her 13 years of consulting experience. Kelly's compliance background includes fully permitting compost and industrial facilities and construction projects for water waste discharges. Kelly has tested field hydraulic soil conditions, and characterized the hydrogeologic conditions at southern California facilities for State of California waste discharge permitting. Kelly has performed condition assessments for surface drainage in the vicinity of sensitive watersheds and designed surfaces facilitating drainage and infiltration basins for onsite stormwater management.
